A man walks into a bar and sees a sign that says, "Free drinks for life! Just complete the challenge." Curious, he asks the bartender what the challenge is.
The bartender replies, "Well, you have to do three things. First, you have to drink a gallon of beer in under 10 minutes. Second, there's a pit bull out back with a bad tooth, you have to pull it out. And finally, there's a 90-year-old woman upstairs who has never been pleasured, you have to make her scream with pleasure."
The man thinks for a moment and decides to give it a shot. He chugs the gallon of beer in record time, then heads out back to face the pit bull. Moments later, the bar patrons hear growling, barking, and then silence. The man emerges, bloodied and bruised, and says, "Alright, so where's the old lady with the bad tooth?"
The bartender shakes his head and points to the stairs. The man heads upstairs and the bar patrons hear screaming, moaning, and then silence. The man comes back downstairs, exhausted but smiling, and says, "Alright, so where's that pit bull with the bad tooth?"
